Answer:

(x + n)^2

Step-by-step explanation:

Okay! Let's get this going!

(x + n ) ^2 is correct because first we get

x^2 and n^2. Yet we need to add one more part to this to make it true which is x * n. We multiply this by two since according to the formula (a + b)^2 = a^2 + 2ab + b^2

Find the value of x and y that satisfy both the equalities x/y=2/3 and y/24=3/4<br> .
egoroff_w [7]

x=12 and y=18 satisfies both the equalities.

Step-by-step explanation:

Given equations are;

x/y = 2/3   Eqn 1

y/24 = 3/4   Eqn 2

Multplying by 24 on both sides of Eqn 2

24*\frac{y}{24}=\frac{3}{4}*24\\\frac{24y}{24}=\frac{72}{4}\\y=18

Putting y=18 in Eqn 1;

\frac{x}{18}=\frac{2}{3}

Multiplying both sides by 18

18*\frac{x}{18}=\frac{2}{3}*18\\\frac{18x}{18}=\frac{36}{3}\\x=12

Putting both values in Eqn 1

\frac{12}{18}=\frac{2}{3}\\

As 12 and 18 are multiples of 6;

\frac{2}{3}=\frac{2}{3}

x=12 and y=18 satisfies both the equalities.
